Scientists have found evidence that the Asian continent was free of permafrost all the way to its northerly coast with the ...

For millennia, the tundra regions of the Arctic drew in carbon from the atmosphere and locked it in permafrost. That is the case no more, according to an annual report issued on Tuesday by the ...

The Arctic tundra is now emitting more carbon dioxide than it absorbs, according to the latest Arctic Report Card released by ...

The Arctic is rapidly changing from the climate crisis, with no "new normal," scientists warn.; Wildfires and permafrost thaw ...

Here are some key takeaways from this year's Arctic Report Card: Arctic tundra: carbon sink to carbon source. Permafrost is full of carbon that has been locked away by plants over millennia.

But warming air temperatures in the Arctic are breaking down permafrost across the tundra, in some cases, severely. The Arctic report, for example, showed Alaskan permafrost temperatures in 2024 ...

The Arctic permafrost region as a whole — which encompasses tundra and forests — has become carbon neutral over the past 20 years, meaning it’s neither absorbing nor releasing excess CO2 ...

The Arctic tundra has switched from a carbon sink to a source of emissions, according to a NOAA report. IE 11 is not supported. For an optimal experience visit our site on another browser.

Tuktoyaktuk itself now stands face to face with the Arctic Ocean’s increasingly angry Beaufort Sea, and rests atop 1,300 feet to 1,600 feet of thawing permafrost threatening to sink it.

The Arctic is rapidly changing from the climate crisis, with no "new normal," scientists warn.; Wildfires and permafrost thaw are making the tundra emit more carbon than it absorbs. From beaver ...

Wildfires and thawing permafrost are causing the Arctic region to release more carbon dioxide and methane than its plants remove. The tundra is now a global carbon emitter. Cladonia stellaris ...
